Walras wrote that 'exchange under free competition is an operation by which all parties obtain the maximum satisfaction subject to buying and selling at a uniform price'. However, his arguments have been credited towards the creation of the branch as well as the fundamental theories of welfare economics. Note that Smith's ideas were not directed towards welfare economics specifically, as this field of economics had not been created at the time. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it. He is in this, as in many other ways, led by an invisible hand to promote an end which was no part of his intention. In a discussion of import tariffs Adam Smith wrote that:Įvery individual necessarily labours to render the annual revenue of the society as great as he can. History of the fundamental theorems Adam Smith (1776) The theorems can be visualized graphically for a simple pure exchange economy by means of the Edgeworth box diagram. However, attempts to correct the distribution may introduce distortions, and so full optimality may not be attainable with redistribution. The implication is that any desired Pareto optimal outcome can be supported Pareto efficiency can be achieved with any redistribution of initial wealth. The second theorem states that any Pareto optimum can be supported as a competitive equilibrium for some initial set of endowments. one person may own everything and everyone else nothing). However, there is no guarantee that the Pareto optimal market outcome is socially desirable, as there are many possible Pareto efficient allocations of resources differing in their desirability (e.g. The theorem is sometimes seen as an analytical confirmation of Adam Smith's " invisible hand" principle, namely that competitive markets ensure an efficient allocation of resources.
